Questions about this data

How often is TRN short interest updated?

FINRA collects short positions as of two settlement dates a month (mid-month and month end) and publishes them about a week later. Between those dates the figure does not change.

What does short interest as a percent of float mean?

Shares sold short divided by the float, the shares available to trade. When the float is withheld or covers a different share class than the short position, the percent is not computed and the reason is shown instead.

What is days to cover?

Shares sold short divided by average daily trading volume over the settlement period, as published with the FINRA report. It is the number of average days of trading the short position represents. When the report carries no average volume, days to cover is not measured.
